The OTA roll out is currently being seeded in phases so all the regions may not immediately get the update. Also, those having carrier models of the Nexus 6 will have to wait much longer until their specific carriers release the update.

The Android 7.0 brings a host of new features like bundled notifications, improved battery optimisation, multi-window options and more. If you have not yet got the OTA update go to Settings>About Device>System Updates to check if the update is available. Make sure you are connected to a stable Wi-Fi while updating your device.

Until now only Google's Nexus phones have received the update with reports indicating that the rest of the Android devices will only get the update post Google's 4 October event. At the event Google is expected to unveil a host of new products like the Pixel range of phones, an all new Chromecast and Google Home among others.
